MUSIC-ROLL SPINDLE.

Application led May 6,

To all wi/0m t may concern."

Be it known that I, S'ri-iNLEY L. FISHER, a subject of the King of Great Britain, residing in Chester, county of Middlesex, State of Connecticut, have invented certain new and useful In'iprovements in Music-Roll Spindles, of Which the following is a full, clear, and exact description.

This invention relates to spindles for supporting rotating music rolls or spools upon which are Wound note sheets used in connection with self-playing musical instruments. In general the music spool is provided with a socket at each end, which sockets receive the supporting spindles, the spool being driven by one only of the spindles, usually that one at the right hand side of the spool box. This applicationhas particular reference to the left hand or non-driving spindles of the general ktype shown in my copcnding application, No. 130,469, filed November 9, 1916, (Patent No. 1,t02,060y Januaryy 3, 1922) of which this application is a continuation in part.

The sockets provided in the ends of the music spools may be of varying sizes so that the supporting spindles, which of necessity must be small enough to t the smallest socket, do not fit the larger sockets accurately. Such a loose fitting of the parts results in the roll dropping or shifting about on the spindles, particularly when it is being rewound, yWhich causes a distressing knocking or chattering noise.

One of the objects of the present invention is to obviate this disadvantage by the provision of a non-driving spindle Which is resiliently pressed into engagement With the Walls of the music roll socket. The roll socket engaging member, While fitting the smallest sockets provided in the spools, .will nevertheless be tightly engaged With larger roll sockets.

A still further object of my invention is to provide a left-hand or non-driving spindle of novel and simple construction, which Will accurately fit roll sockets of varying sizes. Y

A still further object of my invention isk to provide a spindle of the type described with a spring-pressed roll rocket engaging 1921. serial No. 467,342.

member Whichwill automatically be moved into position to engage lthe Walls of the roll socket and will not require a manual adjustment for this purpose when the roll is in serted. f

To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawings:

Fig. 1 is a fragmentary front elevation of a spool box providedv with a roll supporting spindle embodying my improvements;

Fig. 2 is a sectionalview of my improved left hand spindle; i

Fig. 3 is an end view of the same;

Fig. t is a detail view of some parts of the spindle;

Fig. 5 is a fragmentary front elevation of a modified form of my invention;

Fig. 6 is a sectional view of the spindle shown in Fig. 5; andy Fig. 7 is an end view of the same.

I have selected .to show in a preferred form of my invention, a spool boX 10 of usual form provided With the side frame members 11 in which are slidably mounted spindle supporting shafts 12 and 13. A music roll 14e. upon which is Wound a note sheet 15 is shown supported by the spindles 16 and 18 Which may be more fully described hereinafter. The note sheet is, in operation, Wound from the spool 141 by a take-up spool (not shown) in the usual manner.

The right hand spindle 16 Will be provided With suitable driving means such as the usual driving tenen, as is shown in my copendingv application previously referred to. This spindle is also provided with a collar or sleeve member 17, the periphery of which abuts the flange of the music roll about the usual socket to correctly center the same. As this application is not particularly concerned with this right hand or driving spindle, a fuller description thereof will be unnecessary.

The left hand or nonfdriving spindle consists of a barrel member 2O Which is secured in a suitable Way upon the end of the shaft 13. This barrel member is of cylindrical form and has mounted therewithin a bushing 2l which projects from the barrel at its forward end and has provided thereon a shoulder 22 which projects over the peripheral edge of the barrel 2O and makes abutting contact with the face oi the spool ilange 223 adjacent the roll socket 2l. The bushing 2l is provided with an annular recess 25 near its rear end and a pin 26 is passed through the walls of the barrel member and into this recess, so that rotation of the bushing within the barrel may be permitted and at the same time withdrawal of the bushing from the barrel will be prevented.

YWithin y a cylindrical bore within the bushing is mounted a roll socket engaging member 2S, which consists of a plug or body member 29 machined to iit closely within the bushing, carrying the head 30 ot' this member upon a plurality of resilient spring members 3l, which are attached to the plug 29 at their rear ends. The member 30, as shown in Figs. 2 to 4, is tapered toward the music spool so as to` present a surface trusteconical in shape and is segmentally divided into a plurality of parts, tour, as shown in the drawing, one ot' which is carried upon each of the springs 31.

The barrel 2O is mounted within a bushing member 32 supported in the side trame of the spool box so that it may be moved in the direction of the length of the shaft 13 to permit the insertion or' the music roll between the spindles. This spindle 1S may be mounted in the the well-known manner so that it will then be resiliently moved toward the roll to properly engage the same. As may be inferred from the foregoing, the socketengaging member 30 will, to some extent, enter within the roll socket 24C, while the flange 22 upon the bushing 21 will engage the face of the roll about t-he socket. lVhile the spring members 3l will normally retain the segments et' the head 30 expanded, as shown in Fig. 3, so as to engage the side wall of the roll socket, they may be 'forced toward each other to some extent, when this member is moved within the socket, depending upon the size thereof. lt will, however, be obviousthat due to the expanding action of the springs upon the segments oi' the head well as due to the tapering shape ol the head, the latter will always be kept in accurate engagement with the side wall of the socket. The shoulder 22 by engaging the face of the roll will, in connection with the right hand spindle, accurately center the same, and the note sheet l,`with relation to the tracker bar.

in Figs. 5 to of the drawings, I have shown a modified form of my invention, wherein, likewise, the supporting shaft is provided with a barrel member containing a bushing rotatably mounted therein, which isprovided with a shoulder to engage the lace et the roll and which carries a springpressed tapering roll socket engaging member.

ln Fig. 5, l have shown the side frame member of the spool box provided with a bushing 33, in which is slidably mounted the shalt 13, which supports the lett hand end oi" the roll. The shaft ll has secured thereon a barrel member Sel in which is mounted a bushing l5 provided with the recess i6 near its rear end. A screw 37 is inserted through the barrel member, the end of which enters the recess 3G to permit rotation ot the bushing 35, but preventing its witl'idrawal from the barrel. rl"he bushing 35 is liared at its forward end to provide a seat 3S) and an annular shoulder ll() to engage the tace oiE the music spool in a manner similar to the shoulder upon the bushing 2l. A tapered roll socket engaging member ll truste-conical in shape is provided. upon its rear face with a plug or stem el2 which is received within the bore olE the bushing 35. The stem l2 is proviued with a. socket 43 which seats a spiral spring ll reacting against the bottoni ot the bore in the bushing. rlhe roll socket engaging member ill will be slidably received within the liared portion 39 of the bushing when it is moved to the lett in Fig.

G against the tension ot the spring elet. The

stem is notched at to receive a pin "LG driven through the wall of the bushing to prevent the ejection ol: the roll socket engaging member by the spring fle. This notch is, as shown, considerably longer than the diameter of the pin, so that a slidablc move` ment ot the member all with relation to the bushing is permitted.

rlhe `operation ot this device will be similar to that of the embodiment et my linvention shown in Figs. l to rlhe shaft 13, as shown in Fig. 5, may be moved to the lei't to permit the insertion of the spool between the spindles. 'When this has been complished, the shaft is again moved to the right by the usual resilient means, so that the roll socket engaging member will enter to some extent the socket 2l in the spool, while the shouder r10 will engage the tace of the spool about this socket. 'When the flange et() abuts the ,tace of the roll, the movement of the shaft 13 to the right will, ot course, be determined, but the roll socket engaging member ll will have an independent movement within the bushing, due to the action of the spring llby which ,it will be resiliently urged to the right to snugly engage the side wall ot the socket. lt will be obvious that in both forms ot my invention this roll socket engaging member is resiliently mounted so that it is urged at all times into snug engagement with the roll socket. This cngag lent is due to the lateral expanding action upon the segments oii the head 30 by the springs 3l in the' one lili) case and to the movementof the socket engaging member longitudinally of the supporting shaft by the spring 44 inthe "other case. The roll socket engaging members are in both v`instances carried upon plugs which are mounted Withinl the bushings which rare in turn rotatably` mounted in the barrel members.

If desired, some anti-friction means may be provided between the rear end of the bushing and the forward end of the shaft 13, such as the balls i7 which may respectively be spun into the shaft and bushing. It vvill be obvious that as the bushings which carry the roll engaging members are rotatably mounted with respect to the shaft 125, this shaft may or may `not be rotatably mounted Within the frame of the spool box'.

Thile I have shown and described some preferred embodiment-s oi'iny invention, it is to be understood that the same will not be limited thereto in all its details, but is capable of many modifications and varations which Will come Within the spirit of the invention and Within the scope of the appen ded claims.
